Solving the #ClimateCrisis too expensive?
Think again.

#COVID19 recovery stimulus dwarfs green energy investment needs for a 1.5°C-compatible world

A thread on our new scientific analysis published in @ScienceMagazine
In the wake of the economic crisis caused by the #COVID19 pandemic, governments have pledged unprecedented amounts of economic recovery and stimulus.

We tally up all pledges and compare them to what we would need to transform the global energy system to #netzero by 2050 (2/n)
We show that the 12.2 trillion USD in pledged #COVID19 recovery is roughly double the amount of all low-carbon energy investments required globally over the next five years to put the world on track for a 1.5°C pathway. (3/n)
Comparing the 12.2 trillion USD #COVID19 recovery stimulus to the additional investments needed to move from our current global high-emission path onto a Paris-Agreement-compatible track shows the opportunity governments have today, as stimulus is eight times larger (4/n)
Governments first concern after this pandemic is to boost employment, scale rapidly and make their economies more resilient to future shocks.

We highlight how green investments provide exactly what governments are looking for. (5/n)
A climate-positive recovery guiding the world onto a path towards #netzero CO2 by 2050 is well within the #COVID19 budgets currently pledged.

We show the opportunity to keep warming to 1.5°C when recovering from this pandemic - but governments have to respond adequately (6/n)
The actual study (paywall - sorry):

THREAD: In a new study in @nature we present a way to avoid the bias that burdens future generations and the risky strategies that current #climate change mitigation pathways suffer from.

A #climatetwitter explainer

#Fridays4Future #ClimateStrike #ParisAgreement

(1/n)
Existing #ClimateChange scenarios focus on reaching a target in 2100

but by doing so weirdly suggest that the best way to achieve a #climate target is to delay action first, miss it over the next decades, and then to try to make up for it later

(2/n)
This puts put a disproportionate burden on future generations, who:
-will suffer higher #climate impacts in their lives
-are burdened with later cleaning up the mess by actively pulling #CO2 out of the air

This strategy is very risky and can be avoided
