Who else is involved?

Already, millions of people have lost their homes and their livelihoods as a result of climate change. Yet government action remains profoundly inadequate and fails to secure a safe and just future for all. With climate change now rocketing back to the top of the political agenda, thousands of people from around the world have to decided to fast once a month to stand in solidarity with those already affected. We want to tell world leaders that they need to do more to solve this crisis. This should include committing to new action at the Climate Summit of the United Nations Secretary General Ban Ki- moon in September and stepping up to set in place a fair, ambitious and binding global climate action plan in Paris in 2015.

Why fast for the climate?

What we fast for

We Fast for the Climate to send a message to governments that people from all walks of life, from all corners of the globe, and from all faiths and creeds expect climate action. We demand a just transition to a safe climate future. To achieve this, we call for:

  • World leaders to use the 2015 climate talks as a chance to set the world on a path to completely phase out of fossil fuel emissions and phase in of 100% renewable energy by 2050, with sustainable energy access for all.
  • People worldwide to reconsider their own consumption patterns and – in particular – adopt a mindful, conscious relationship with food; and
  • The leaders of those countries who are less vulnerable to the climate crisis to take real steps to meet their commitments to the world’s most climate vulnerable people.

Already, millions of people have lost their homes and their livelihoods as a result of climate change. Yet government action remains profoundly inadequate and fails to secure the benefits a clean energy revolution would deliver for people and the planet.

The time to solve the crisis is now. 2015 is a unique opportunity to set the world on track to a safe climate future. We expect countries to cut carbon pollution and to secure a renewable energy supply by 2050. We want individuals to continue to lead the way by adopting climate solutions through their own consumption. We expect richer countries to help poorer nations reduce their own pollution and adapt their communities to climate impacts, while we urge all world leaders to work together in order to ensure the planet is a safe and better place for future generations.

Personal Reflections on Fasting: “Why I’m fasting for the climate”

07-Martin-Kopp-LWF-delegate-to-COP19-from-France-01“Fasting made climate change real for me, opened my eyes and brought me closer to my neighbours. This is one of the reasons why fasting once a month is interesting: it raises one’s awareness on a regular basis and not only when extreme weather events happen. As long as you share your commitment around you, you help raising awareness about climate change. And that is, after all, what makes your fast matter.” — Martin Kopp.

Fast For The Climate, here’s how it started: Thousands of people began to Fast For The Climate last year in solidarity with victims of extreme weather events such as Typhoon Hai-yan, and to show strong public will for urgent and decisive action on climate change.

See a video of Yeb Saño’s moving speech in the 2013 climate negotiations in Warsaw.

When Typhoon Haiyan/Yolanda had just devastated the Philippines in November 2013, then climate commissioner Yeb Saño was at the UN climate talks in Warsaw. His own family was caught up in the disaster that killed thousands and destroyed homes and livelihoods across the country.

In a moving speech, Yeb said he would not eat until the Warsaw conference ended or delivered actions that would ‘stop the madness’ of the climate crisis. So long as the people he represented could not eat, nor would he.

Hundreds of others from around the world chose to fast with him in solidarity.

Despite this, the Warsaw meeting saw countries actually winding back their climate commitments, seemingly in denial that all countries will need to commit and contribute to the comprehensive, global climate action plan which is due in Paris in 2015.

The Fast For The Climate has grown into global movement with participation of youth groups, environmental groups and faith-based groups, who all want urgent action on climate change by governments this year.

Choosing not to eat doesn’t mean sitting around feeling miserable! What some people say on fasting: “It’s a rich personal experience, it gives a sense of revival, and cleansing, and joyfulness.” “To bring climate change under control we need to exercise self-control, we need to act together, fasting enhances our focus and determination.” “I feel physically in solidarity with people who are affected by climate change when I fast, it gives us a glimpse of the reality for millions, a feeling of connection and urgency.”Women sing a song about climate change in Malawi.

How to Fast Our understanding of fasting is going without something voluntarily. In this case we are mainly talking about going without food. Most of us are fasting on the first of each month, for 24 hours. But there is no right or wrong way to do it. Some people are skipping a meal together once a month. Some people are fasting from carbon consumption and production. Some people are fasting from food waste. How are you going to do it?

Top tips for fasting

When we fast

We will fast on the first day of every month, until countries agree a comprehensive, fair climate action plan that puts the world on a pathway to phase out carbon pollution.

From the start of the 2014 Lima climate talks to the start of the 2015 Paris talks, we also have a rolling fast moving from Lima to Paris, with one person fasting each day.

We fast for one day each time. Many of us interpret that as a 24 hour period from midnight to midnight. Others fast from dawn until dusk. How long you fast is up to you. You know your limits, and only you can choose what is safe for you.

How we fast

Fasting is giving something up voluntarily for a fixed period. Mostly for us, that means giving up food for a day, but we encourage our fasters to define their own limits. It is important to us that our fasters are safe and healthy.

Fasting from food

There are different kinds of food fast:

1. Normal fasting: The most common form of fast is to give up food, but continue to drink liquids. Some people drink only water, but others drink juice, clear liquids or even fresh juices or smoothies. This is the kind of fast we encourage for most people. It’s up to you to set your own limits.

2. Partial fasting: Some people choose to continue to eat some food, but restrict what they eat. This could be giving up some meals, or giving up some foods – such as going vegan or vegetarian for a day, or only eating locally grown food. If you do not think you should give up food for a day due to health concerns, family or work responsibilities, or any other reason, we encourage you to consider this option.

3. Absolute fasting: This type of fast is where you abstain entirely from food and drink. We do not encourage people to try this kind of fast. If you wish to do an absolute fast for the climate for a day, we strongly recommend that you speak to a medical professional first.

Ultimately, Fast for the Climate is a movement. To build our movement, we need to look after our health and be safe. That’s why we encourage you to set your own limits. Normal fasting for a day from time to time doesn’t harm your health and many people believe it is beneficial to your health. But, if you are suffering from any serious health problems, do check with your doctor before fasting.

Tips for fasting from food

  • Don’t eat too much the day before, but ease yourself into it with a light meal beforehand so it isn’t too much of a shock for your body.
  • While you are fasting, drink plenty of water or other liquids.
  • Limit your intake of caffeine or alcohol both before and during your fast.
  • Fast with someone else; fasting is normally a deep personal experience, but sometimes it’s good to talk through it with someone else.
  • When you break your fast, ease yourself gently into eating again with a small amount of light food first.
  • Use your body’s feelings of hunger to remind you of your purpose and focus on the reasons for your fast instead of the temporal feelings of hunger.

Alternative fasts

For some people, fasting from food might not be practical, safe, or possible. And that’s okay. If you are one of those people, we encourage you to to consider alternative ways that you can fast. What could you give up for a day? What about giving up caffeine, or alcohol, or even just chocolate? All of these things will be affected by climate change. These are just ideas – what you give up is up to you.

One of the most popular alternative fasts within our movement is a carbon fast, where people deliberately and voluntarily reduce their carbon footprint for a day. While it probably would be almost impossible to absolutely eliminate your carbon emissions, you can reduce them drastically. As with our fast from food, you can set your own limits. Here are a few ways to carbon fast:

  • Don’t drive for a day – or, if it’s possible for you, don’t even use any fossil-fuel powered transport and get around by cycling or walking!
  • Don’t use gas or electricity (unless you’re lucky enough to know it comes from renewable sources!) for heating or cooking for day. That’s right – have a cold shower.
  • Don’t use electric lighting for a day.

Think about what parts of your liftestyle contribute the most to your carbon emissions, and see if you can cut them for a day each month – or even more often. Many of our fasters have made ongoing lifestyle changes to reduce their greenhouse gas emissions. Let’s be part of the solution, not the problem!
