~0.35%. That’s the annual methane reduction needed for agriculture CH4 to be #ClimateNeutral. Reduce ~5% annually, we can neutralize all additional warming from ag CH4 since the '80s. WE CAN DO THIS!

GWP* vs GWP100 better describes how #methane emissions impact the climate. Using GWP100 overestimates the warming impact of constant CH4 emissions by 3-4 times.
AND GWP100 misses climate benefits with decreasing emissions.
AND undersells warming when CH4 emissions rise.

Why is GWP* important? From the paper: GWP* emphasizes CH4 reductions can only contribute meaningfully to limiting climate change, as long as CO2 hits net-zero.
GWP* shows the true benefits w/ CH4 cuts. Making the work farmers/ranchers are doing to cut CH4 more significant. 3/

Reducing methane from enteric fermentation and manure in #beef and #dairy (which we are studying at @UCDavis in the @CLEARCenter) are two critical strategies to achieve #ClimateNeutrality with significant co-benefits.

Some feed additives have shown increased production efficiency in #dairy cows in addition to their #methane mitigation benefits. Improved 🐂 grazing management ⬆️ the carbon sequestration potential of rangeland in addition to ecological benefits.

Manure management tech like anaerobic digesters (w/ proper market) are the most carbon-negative fuel for transportation. Anaerobic digestion & composting lessen reliance on inorganic fertilizers & increase soil carbon sequestration. All of these can earn producers additional 💰6/
I have long said that #ClimateNeutrality is possible for the U.S. #beef and #dairy industries. Climate neutrality is a next zero warming contribution, similar to the impact of net-zero carbon emissions.

What is even more exciting is the potential to achieve a net cooling effect by harnessing ruminant animals’ place in the biogenic carbon cycle. Aggressively reducing CH4 will pull carbon from the atmosphere resulting in cooling.

Getting CH4’s warming impact right is not greenwashing. The paper says: Rather than undermine the attention and importance given to CH4 up until now, GWP* underscores the importance of making meaningful reductions in CH4 emissions as soon as possible to meet climate targets. 10/
In fact, more so than GWP100, GWP* shows that increasing methane emissions will increase warming.
From the white paper: A 1.5% annual increase in CH4 emissions leads to climate impacts 40% greater when using GWP* vs. GWP100.

Reaching #climateneutrality in the livestock sector is more attainable than we previously understood & that doesn’t at all take away from the fact that reducing CH4 will help fight climate change. It reinforces that.
