The Recent report from the Intergovernmental Panel on Climate Change (IPCC) — which one of us (Arunima) contributed to — has emphasised the need for enormous change if we are to keep within the 1.5℃ warming limit.
This Paris Agreement goal can currently be achieved Beyond our reach. To achieve it, drastic emissions reductions would be required in all sectors and at all levels.
These technologies are able to address the climate problem in a variety of sectors, including the transport and food industries.
1. Alternative protein sources
The IPCC reportThis article highlights the potential for plant-based diets to not only reduce our emissions but also improve our collective well being.
Plant-based protein sources, including “fake meat” products, are increasingly being produced to mimic the appearance, flavour and texture of animal meat.

How much meat can we eat? New figures show that six countries have reached their peak.
Traditional tofu was made from simple ingredients. CoagulationSoybean milk. A few decades ago, we witnessed the emergence mycoprotein, which is derived form fungus (and has been popularised in the brand Quorn).
More novel alternative proteins require Advanced extrusion techniques and artificial flavours and coloursTo imitate the texture and taste of animal protein
Then there are cell-based meat alternatives, also called “lab-grown”,
cultured” or “in-vitro” meats. These are made by using Advanced bioengineering methods to grow meat cells from a sample (starter cells) extracted from an animal, inside a device called a “bioreactor”.
Cell-grown meat is a new technology. It was on sale for the first time2020 in Singapore It’s not commercially available in Australia yet, but according Reports work has begunBehind the scenes
Plant-based meats have a lower cost than meat from livestock. Produce 30–90% less greenhouse gas emissions, require 40-98% less land, 70-80% less water, and release 85–94% less reactive nitrogen (which can lead to excessive Algal growthThis deprives marine life oxygen.
Australia is the Third fastest-growingVegan market around the world. Australia’s main industry research organisation, CSIRO, estimates the sustainable food market here alone will be worth A$25 Billion by 2030.
Alternative proteins have the second-largest market potential among all the categories in food and agribusiness. They are expected deliver A$5.4 trillion in Carbon and water savingsBy 2030
2. Packaging that is edible and biodegradable
The name implies that edible or biodegradable packaging is food-safe and can be eaten. Edible packaging is made from natural polymers obtained from plants and can be made into many films or coatings. Here are some examples:
Packaging that is edible could not only be more environmentally friendly but also increase the appeal of edible products. Nutritional value of packaged food, by incorporating compounds known as “nutraceuticals” which can improve the nutrient composition of packaged food. Packaging can be improved by adding antioxidants and antimicrobials.
While there is still much to be done to make edible packaging mainstreamed, it has already been proven to be a success. Alternative to plastic bottles for marathon runners.
Only Australia recycled in 2020 16%Plastics Only about 5% of plastics are used globally. 17% of plasticsIn 2015, they were recycled. The rest ended up in landfill, oceans and rivers — damaging land and marine systems — or generated carbon dioxide and other harmful emissions during incineration.
Fossil fuel-fuel based plastics are possible 20-500 yearsto decompose, while biodegradable packaging decomposes within. Three to six monthsDepending on the material.
It’s estimated the global biodegradable packaging market will grow by 17% each year, and be valued at US$12.06 trillion by 2025.
Australia has established a target for 70% of plastic packagingTo be composted or recycled by 2025 and to phase out single-use plastics before 2025. These targets could be supported by innovation in edible and biodegradable packaging.

3. Electric vehicles
While they’ve been a hot topic for a while now, electric vehicles can’t be overlooked.
The IPCCElectric vehicles were identified as having the greatest potential to decarbonize land-based transport. Why? Because electric vehicles are more popular than ever, and because they are cheaper, which has already proven to be a boon. Emissions reduction. And market shares of electric vehicles TripledIn two years.
Australia’s transport and energy sectors account for a significant portion of GDP. More than 50% of carbon emissions are caused by human activities. ResearchShows that electric vehicles can transform the transportation sector if they are paired with a 100% renewable electricity network where all energy is generated from renewable sources.
What’s more, if all vehicles were electric and we had a 100% renewable electricity system, consumers could expect to SaveBased on petrol prices of A$1.40-2.00/litre
Uncontrolled charging is required for electric vehicles, but this can be controlled and uncontrolled. Uncontrolled charging allows users to charge their vehicles at any hour of the day. Controlled charging is only available for vehicles that are registered with the manufacturer. maximising benefitsBy charging during daylight, for instance, when there is plenty of sunlight. It would be necessary to run approximately 16 million electric cars on Australian roads. 205 gigawatts installed capacityIf the electricity source is 100% renewable, it will provide the electricity needed to charge the device.
According to the Australian Bureau of Statistics in 2021, there were 23,000 registered electric vehicles in Australia. This is a decrease of about 5%. 20 million vehiclesIn total. Australia is falling behind other developed nations in the race to adopt this technology.

4. Hydrogen’s vast potential
Solar and wind power are both well-established and feasible options for reducing emissions — and are even CheaperRather than non-renewable resources.
Both are equally valid. Variable energy sourcesThese depend on weather, season and geography, as well as the time of day. This can cause supply gaps that need to be addressed.
Hydrogen, which does not produce carbon emissions when it is burned, is a potential option. Option. It can be made by splitting water using electricity generated from solar and wind sources. It can also be used as a storage medium for renewable energy.
Hydrogen production costs will fall due to the falling cost of renewable energy and the scaling up of hydrogen deployment. 30% by 2030. Further development of hydrogen energy storage technologies could lead towards further ReductionsVariable renewable electricity systems are more expensive.
The IPCC reportThe potential use of hydrogen in aviation to reduce carbon emissions is also mentioned, but it is important to note that this will require technology improvements and cost reductions.
