To keep global temperatures rising by 1.5C, we need to cut emissions by 30 gigatonnes of greenhouse gases every year until 2030.
30 gigatonnes = 30 billion tonnes
A car will produce around 24 tonnes over its life cycle
So 30 gigatonnes are equivalent to 1.25 billion cars. 🧵👇

We obviously can't get rid of 1.25 billion cars every year until 2030.
So how do we reduce emissions by 30 gigatonnes of greenhouse gas each year?
The good news is smart folks have figured this out.
If we focus on just 6 sectors, we can do it. 👇

If we focus on just 6 sectors, we can do it. 👇
Sector 1: Energy
The energy sector can cut emissions by 12.5 gigatonnes annually. And we don't have to wait for any new inventions!
We can do it by shifting to renewable energy and being more energy-efficient.
E.g. solar panels, wind turbines and LED light bulbs.

Sector 2: Industry
Industry can cut emissions by 7.3 gigatonnes annually.
Industry can do this by embracing passive or renewable-energy based heating and cooling systems, improving energy efficiency and fixing other pressing issues like methane leaks.

Sector 3: Agriculture, Food and Waste
New food production solutions can reduce emissions by 6.7 gigatonnes annually.
And shifting diets to a more plant-based (more sustainable diet) and reducing food waste can reduce emissions by more than 2.0 gigatonnes annually.

Sector 4: Nature-based solutions
By halting deforestation, halting the destruction of ecosystems and restoring them, the world can reduce emissions by 5.9 gigatonnes annually.
This would also improve air quality water quality and improve rural economies.

Sector 5: Transport
Transport is responsible for a quarter of all greenhouse gas emissions, and that's set to double by 2050 if we don't act.
The excellent news is 4.7 gigatonnes per year could cut emissions by:
• shifting to electric vehicles
• Walking and cycling more

Sector 6: Buildings and cities
By 2030 buildings will account for 12.6 gigatonnes of energy-related emissions. Most of those buildings haven't been built yet!
By making cities and buildings fit tomorrow and updating existing buildings, we can reduce emissions by 5.9 gigatonnes.
